tus, the owner of the apparatus invariably finds the results of the depredations of a certain class of individuals who interfere is with the coin control for the purpose of beating the machine.

Many persons, otherwise honest, are inclined to use their most agile thoughts to defeat the urpose of the coin control.

1U} Approamed from a psychological point of view, the most eiiicient means for terminoting such improper efiorts is to penalize the tamperer and take away the benefits of the device, or to make it appear such tampering has broken the apparatus. None other than an actual thief ordinarily will tamper with an apparatus after the ehect of his ef= forts tends to make him believe that he is destroying, breaking, ordisarranging such apparatus.

It is with these ideas in mind that the present combination of elements was devised, and from the foregoing discussion, it will be apparent that the invention relates to a radio apparatus intended for hotels, amusement parlors, and elsewhere where the machine may be located for the operation of the public subject only to the necessity for placmg a coin therein.- prior to rendering the device operative.

In such a device, it is necessary to provide a coin detector which is used in conjunction with the radio apparatus itself, and there must be such association between the coin detector and its parts and the radio circuit that the radio apparatus can not be worked until the coin apparatus shall have been properly actuated. Further, there must be a time determining element, such as a clock mechanism or the equivalent thereof, to regulate the period over which the radio circuit is closed upon actuation of the coin detector mechanism. In order to carry out the objects of the invention hereinafter recited, it is necessary to break the radio circuit coincidentally with any improper manlpulation in respect to the coin detector.

ncluded in the objects of the invention, therefore, are the provision of the followmg:

A coin detector in association with a radio circuit adapted to break the radio circuit as an incident to improper manipulation of such coin detector;

A novel mechanism adapted to be con 6% trolled by a coin and comprising" a coin detector, a time limiting; element, and radio circuit which is broken independently of the time controllin element when improper inanipulation oi the coin detector is sad;

A new method of breaking; a radio circuit throug h the employment of a coin con trolled radio apparatus;

An unique apparatus comprising a coin detector, a time fixing element, and a radio circuit, and in which there are means for breaking the radio circuit as an incident to improper actuation of the coin detector;

Improved means for breaking a circuit in a radio circuit actuated by a coin controlled element;

The provision, in combination with a clock mechanism, of a switch mechanism actuated thereby having novel clock stopping means; and

The provision of novel mechanism for definitel controlling the period of time over whic a clock mechanism controlling the activities of other elements may operate.

These, and such other ob'ects as may hereinafter appear, are obtaine by the novel construction, combination, and arrangement of the several elements which constitute the invention. g0

Like reference characters are used to indicate similar parts in the drawing and in the following specification.

Reference should be had first to Figure 1. For purposes of indicating the application of the present invention to a conventional radio set, a perspective view of a. commercially wellown radio set havin the present invention applied thereto is s own. In such illustration, the cabinet is indicated by the numeral 20, the tuning handle or control by the numeral 21, the compensator by the numeral 22, and the volume control handle by the numeral 25. The open dial for reading the'wave len hs and through which in most sets a sea e upon which a light is visible, isindicated by 24.

The cabinet 20 is so made that access thereinto may be had only by key, there being a lock arranged in association with the cabinet 20 whereb the cabinet is closed against thieves an the inquisitive. The cabinet ma be of any suitable material but preferably is of metal. Any suitable lock may be employed on said cabinet 20, none being shown and the device may open at the top, the bee c, or the bottom, as is preferred.

In an end panel 26 of the cabinet 20 the mechanism forming the subject matter of the present invention is installed. For convenience, the present invention will be called the timmg element and will be designated generally by the numeral 27. The invention may be manufactured as a unit capable of installation in any selected radio set.

In order to meet the demand for the use of a device of this character and to satisfy the demands of the reatest possible number of customers, it has een found desirable to employ two -coin actuated control mechanisms 28 and 29, one of which is adapted to be actuated by a nickel or dime and permitting of a five or ten minute operation of the device, and the other actuated by a quarter and permitting of a half hours use of the ap aratus These coin detectors are mounted s1 e by s1de upon a anel 30, such adapted to be inserted into and firm y secured in an o ening provided therefor in the cabinet en 26.

Said panel 30 includes a plurality of fastening members 31 which, in the'present instance are screws welded to the back of the panel 30 so that there will be no ossibility of removing the panel 30 through t e agency of its fastening means from the end 26 and the outside of cabinet 20.

At each end of the anel 30 are angle irons 32 which may be we ided into proper position and which provide guide members for the frictional engagement thereon of a cover 33'. The cover 33 comprises a top 34, a back 35, ends 36 and 37, and an abbreviated botmember 33 provides a tom section 38. Such shield for the whole upon panel 30 andis ing the insertion, or either of them, which mi the radio circuit which is disposed to one side thereof, the radio circuit being to the right of the portion 35 shown in Figure 6.

The abbreviated bottom section 38 is necessary in order that coins passing throu h the detectors 28 and 29 may drop out of t e mechanism into any suitable receptacle which mechanism disposed effective for reventthrough the coin etectors of a wire or other element may be placed beneath the orgening inter-' mediate the panel 30 and the ack portion 38. No such receptacle is shown for it forms no part of the subject matter of the invention.

Mounted in the back 35 is a suitable socket 39 into which may be inserted a plug 40, the socket 39 being of any approved type whereby panel.

ght possibly attain contact with 1 memos the plug normally emploged may be attached thereto. The current to into and out of the present apparatus may be the normal lightsocket current with which most radio sets are now energized and thecircuits herein described comprise one having two switches which are controlled by the present mechanism, one which .is normally open and ada ted to be closed by actuation of either of t o clock mechanisms associated with the coin detectors 28 or 29, and the other which is normally closed and which is o ened each time there is ,amovement of eit er of the handles of the coin detectors 28 or 29 as will hereinafter be ointed out.

A radio circuit 18 neither illustrated nor described as this appears unnecessary. One side of the socket may lead to a source of energy and the other side to the radio cirsuit employed and through said radio circuit to t 1e other side of the source of energy.

As the mechanisms with which the coin detectors 28 and 29 are associated are identical in structure and in their employment in the present apparatus except that one takes longer period oi time to operate, only one thereof will be described iully. This will prevent the duplication of description, will of course be understood in advance that the circuits hereinafter mentioned are so errenged that either coin controlled members 28 or 29 may close the circuit entering through the conduits carried by the plug 40 to the radio circuit, one for a short period or? time and the other for a longerperiod oi time, but that such circuit will be broken by manipulation of the handle of either of the coin detectors 28' or 29.

From one of the conduits carried by the plu 40, a short cable d1 is energized. This cable 41 is suitably connected to a spring stationary contact 42 which is disposed upon a bracket 43 u on panel 30. Saidcontact as is insulated 'rom bracket 43 by sheets of 'nsulation 45 and 46. A second bracket 17 is suitably afixed to the plate 30, and this is for use in association with the second coin detector irnechanism An ancillary short cable 48 is disposed so as to energize a sec ond contact 42 of the same nature and actuated in the same manner as the contact 42 dis osed upon the bracket 43.

ach oi contacts 42 is fixed, as indicated, and is adapted to be impin ed by movable s ring contact 49, each 0 which has a \Xshaped hump 50 which normally engages the tip of fixed contact 42. The spring in said contacts 49 is such that it urges se aration of contacts 49 and 42, and in orv er to maintain contact therebetween, it is necessary to provide a positive means to counteract the urge of the spring tension.

Contacts 49 have an elbowed supporting section 51 which is secured upon an angle iron 52 anchored upon a second angle iron 58, the latter being suitably attached to the panel 80 the angle irons 53 and 52 conjointy provi in a housing beneath which certain of the mec anism hereinafter described is dis osed. At the rear thereof, they support a 0 8:]; mechanism hereinafter also to be descrl The elbowed section 51 of contact 49 is insulated from the angle iron 52 by sheets of insulation 54 and 55or by any other suitable insulator imilar construction will be foun sides of Figure 2.

From the elbowed section 51 there is a cable 56 which extends to a switch member or circuit breaker controlled by the clock means.

mechanism. Said cable '56 is connected to as fixed contact 57 in said circuit -breaker which contact is mounted upon fiber. There is at one end of the contact'57 an extension portion 58 to which the cable 56 is electrically connected and at its other end is an ofi'set portion 59 where electric contact with a movable member is made.

Said member 5? is mounted upon, as indicated above, a fiber sheet (hwhich is indicated as 6d) and upon such s set 60 and opposed to and in reverse position to the contact 5? is a second contact 61 having an extension 62 to which a conducting cable is attached. Said contact 61 has an offset portion 63 for the enge ena nt of a movable contact'di which movcible contact is pivoted at 65 and is provided with spring 66. Member 64: is adapted to bridge contacts 5'? and 61 to establish electrical connection tlierebetween.

The radio set in association with the device is adapted to operate only, of course, when there is electrical contact between the movable contact 84 and the ofiset portions 59 and 63 of the fined contacts 5'? and 61. From the extension portion 62 of the left hand mechanism shown in Figure 2, there is a cable 67 which extends to the contact 61 on the right hand section or part of the appsat both the right and left hand ratus from which latter contact 61 there is a cable 68 to the opposite side or" the socket 39 70 which might be integral but which is illustrated as comprising an angle iron 71 secured upon a second an 1e iron 72, the latter being suitablyattache to the panel 30. As is clear from Figure 6, the contact 64 and its pivotal mountin 65 are insulated from the contacts 57 an 61, and also that the movable contact 64 is insulated from all other parts of the device, except when the circuit breaker is in closed position when said contact 64 engages contacts 57 and 61.

Forthe actuation of the said movable conact 64 it is necessary that the clock mechanism shortly to be referred to be partially wound. Intermediate the clock mechanism, which is in part mounted upon the bracket 70, and the movable. switch 64, is the coil :pring 66 which is anchored at one end upon a fiber disc 78, shown in Figure 4, and at 1ts other end u n a prong it the upper end of said movab e contact 64. The c ock mechanism which actuates the. disc 73 is so d1sposed that so long as it is actuating and the radio circuit is closed for the period provided for by the amount of money paid by the user through detectors 28 and 29 there will be a tension upon the contact 64 whereby 1t Wlll be held in physical and electrical contact with the offset portions 59 and 63 of fixed contacts 57 and 61, but at the instant of ex piry of the period for which the user has paid, the disc 73 upon which the spring 66 1s anchored will have been moved by the clock mechanism to a position where such tension shall have closed and the tension has become such that it urges the contact 64 to disengage itself from contacts 57 and 61. The instant that the dead center of the contact 64 intermediate sions referred to shall have been passed, the tension upon the spring 66 will break the circuit, the break in circuit being of an 1n- ".ta'nt nature. The parts will be moved by the actuation of the sprin 66 from the dotted line position shown in igure 5 to the full line osition shown in the same figure, thus opening the circuit to the radio receiving device. This will be a quick break and prevent arcin in the set WhlCh might occur in the event t e contacts were slow to separate.

The position of the spring member 66 upon the disc 73 where it is anchored b a peg 74 which is firmly secured in the H r material of the disc necessarily determines the riod of time over which the circuit ma be c osed by the switch full illustrated an described in Figures 4 an 5, and hereinabove described.

By reference to Figure 4 which is a detail of such disc which iscontrolled by the clock mechanism it will be instantly alpparent just what movements the disc 73 ma es from the position attained as an incident to operating one of the coin controlled members 28 or 29 to the time that the circuit is broken by the clock mechanism running down to a limited extent.

To actuate said disc 73 there must first be deposited in the coin detector 28 or 29 the proper coin. The handle 75 of thecoin detectors 28 or 29 is then moved in a clockwise direction. Mounted upon the coin detector and influenced by the two ten-- meaaos is a drum 76 best shown in Figure 11. About the drum and anchored thereon is a coil spring)", the other end of which s ring may be anc ored upon the member 72. ovement of the handle 75 of the coin detector, which movement of course causes the remainder of the parts thereof to be actuated, increases the tension upon the sprin 77 so that at the instant the handle 75 is re eased the coin detector is urgin ly returned to its normal position, a fixed position which it continues to occupy unless someone manually moves it again in a clockwise direction. In such fixed position contacts 42 and 49 are in engagement.

In addition to the drum 76, just referred to, there is a second drum 78 which has at one side thereof an extension or lug 79. Upon such extension is a stud or a roller bearing 80 which bearing is adapted to impinge sprin contact 49. insulation, t e member 49 is supplied with an insulating back or sheet 81 which is tied or fastened thereon by means shown at 82.

has electrical connection between the member 49 and the coin detector is prevented.

So long as the coin detectors 28 or 29 are in their normal position the stud 80 impingfs the insulatory material 81 and urges the um 50 of the contact 49 into engagement wit stant that the handle 75 is moved in a clockwise direction, the elbowed spring portion 51 causes an instant disconnection whereby the circuit hereinabove referred to, if closed, is broken. Thus, when anyone tampers with the handle by moving it from a position away from that at which it normally rests, the circuit to the radio receivin set will be broken during the operation of said set as an incident to the payment of the price for such use.

The instant effect of such movement is to cut oil the electromotive force by which the radio receiving set is o erated and the music or speakin voice which is bein heard thereon is stille The psychologicifi efiect of the breaking of the circuit and the stilling of the radio receiving set generally is such that the person who has manipulated the handle 5, out of curiosity, coincidentally releases such handle not to again interfere with it so long as the set contlnues to function.

Upon the tampgrer who is looking for an opportunity to at the coin detectors, the e' ect is generally such discouragement because he reasons that he has broken the device and has lostthe benefit derived by the spending of his money. Usually his tampermg 0 erations also will cease with the break- For purposes of in o the circuit. The instant that improper in uence u on the handle 75 is removed, said handle wilFrevert to its normal osition and the receivin circuit will be esta lished. In a few secon the time required for the elecmade to operate memos trodes in the tubes to again become heated, the radio set will be heard, provided the clock mechanism has not, in t e meantime, broken the receiving circuit through the movement of contact 64 from the contacts .57 and 61.

When a proper coin is placed in either of coin detector 28 or 29, such detector will be movable in a clockwise direction sufllciently far to discharge the coin therethrough. When such is the case, the member 80 will impinge upon an arcuate member 83 which is amxed to the main spring shaft 84 of the clock mechanism. Rotation to the extent which the coin detector may be moved imparts an arcuate movement to the member 83 whereby the main spring of the clock 85 is wound to operate the clock mechanism p over the period of time which such mechanism should operate by reason of the position of the sprin 66 upon the disc 73.

'llbc'clock mec anism illustrated which is shown as anchored u on the members 7 3 and 52 is that of the or inary alarm clock with the substitution in place of the hair spring, of a weight 86 balanced upon the hair spring shaft whereby to insure an instant starting of the clock mechanism.

A full understanding of the clock mechanism can be had by an examination of the drawing, it not being believed that it is necessary to say more than that there is a plurality of gears intermediate the main spring shaft and the shaft for the weight 86 whereby the urging force of the main spring 85 is controlled over a period oi time, so that a relatively small amount of ener stored in thespring 85 by its manual win ing may be the clock mechanism herein illustrated over suitable periods of time.

When the disc 73 attached to the main s ring shaft 84% shall have actuated the movable contact 64 in the circuit breaker, said disc '7 3 has permitted the travel of the clock mechanism the timelimit prescribed therefor. The clock mechanism itself has sufiicient force to continue to operate until shortly after the circuit is broken by the actuation of the member 64 when the clock mechanism is stopped by reason oi? resistance to the movement of its main shaft 84-. obtained in the follow ing manner.

For the purpose of regulating to a nicety the periodot time which the clock movement may run after the circuit breaker disclosed in Figures 4: and 5 shall have been operated in terminate the rlow out eleotromotive force to the radio tubes, an adyusting screws 87 clearwhich actuates the circuit breaker., It is not objectionable to permit the clock to operate for a moment or a fraction of a moment after the circuit breaker has forced the discontinuance of the flow of electromotive force to the radio tubes in order to avoid the necessity for overly line adjustments.

It is quite manifest that theturning of the clock shaft 84 as an incident to the impinging of the member 80 thereon need be over a relatively small angle in order to attain either a five or ten minute or. thirty minute playing period for the radio set. These extremes, one the minimum and the other the maximum, have been adopted as being consistent with the ordinary demands of the average listener eilther in a hotel or in a public amusement ace.

At the instant member 83 engages screw 87 the clock stops and cannot thereafter be made to run until a coin detector 28 or 29 is actuated. Of course, there is an an le of movement of member 78 during whic the lug 80 does not impinge member 83, this being That type of coin detector shown in Figures 1, 6, 7, 8, 9, 11 and 12 is on the same order of that shown in the patent to A. D. Antoine and O, Travis, numbered 1,372,666, dated March 29, 1921, and entitled Check detector for coin actuated machines.

lhe coin is adapted to be received in a pocket and conveyed in an arcuate path by a carrier 101. The ath of travel is in the direction shown in e arrow in Figure 9, the device being su plied with a plurality of means whereby s ugs and blanks may be detected. As these latter comprise no art of the invention, theyare not describe it being essential only in the coin detector that when no coin is therein contained,.there be sufiicient play in the direction of the arrow whereby the contacts 42 and 49 may be separated. A stop means for preventing the rotation of the device in a counterclockwise direction beyond a fixed point hereinabove stated to be its normal position, is also reuired but such stops are common in allcoin etectors.
